Its main advantage is obvious: It is compact and therefore takes quite easily while traveling. There are even running on battery just as effective as taking the condition to take a stock of good quality rechargeable batteries. In return, it is relatively noisy but it never bothered baby in her naps.
This maxi pack adds a second connector to allow simultaneous use of nipple shields. But beware, the performance of this breast pump is much more limited than the models available in hospitals / maternity, it is likely that the simultaneous use is not working or wrong. Nevertheless, it always helps to have a second breast shield on hand to limit the number of daily sterilizations.
The pack also adds a pacifier calmed brand. Too bad for us: Our daughter has never wanted to because it was too weak to breastfeed directly and visibly the same problem is replicated here.
In the end, the picture is mixed: The swing model is an excellent pump. But the additions in this pack were not of much use. I probably would have done better to take the base model by purchasing a few extra accessories separately. Finally, I leave 4 stars because the breast milk remains the essential component of this purchase.
